OK I'll try this

libdir is the first lib listed in the startup list

I just want to use the .pdsettings file I was using -- at least all my 
old paths are listed there so I'm fairly certain I was using this

not sure I follow...if my paths are declared in a patch how can I call 
an external from a lib that is being used by that same patch? wouldn't 
it be better to have everything (externals, libs etc) load in at app launch?

yeah I did as well and only used Jack when talking to my USB audio card
but now since the ALSA OSS emulation layer is no longer in the kernel I 
suppose I'll need to use Jack for everything - which is not a problem 
just have to get in the habit of using Jack to point to my various devices

question: if there is no longer an ALSA OSS emulation layer in the 
kernel and never was ALSA support
why does the GUI still have OSS and ALSA as selections in the pull down
